' This invention relates to a method of making heels peculiarly, although not necessarily, applicable to the manufacture of heels from the cheaper heel-stock materials such leatherboard or an analogous leather or paper composition.

For some years a large number of heels have been mad from leat-lierboard, that is, a majority of the lifts are of leatherboard and leather is employed only as the top-lift or possibly also as the lifts just adjacent the top lift. Various ways and means have therefore been devised to produce the required heel-lift blanks from the large sheets of leatherboard which are rolled at the le'atherboard mill. The method most in use, 2'. 6., dinking the blanks from the sheets, is a slow process because blanks of different sizes must be dinked separately and in quantities, a process of selection having then to be resorted to in building heels. of particular styles, for example the Cuban or military styles.

An object of the present method is to avoid the necessity of preparing or maintaining any stock of heel-lift blanks and to produce such blanks from the heel-stock material only in such quantity as may he needed for a single heel. The invention also has for an object a method of producing heellift blanks which simultaneously provides suliicient blanks, graded as to area if desired, for a single heel, the heel-stock material being'so prepared that this process may be repeated indefinitely.

Broadly the method contemplates procuring 'suflicient heel-lift blanks to form a complete heel, Whether it be a straight or a tapered heel, from a source of heel lift supply, which may be a series of strips of heelstock material, depositing said lifts in a row to facilitate an immediate collection in a stack, superposingthe lifts on each other, and securing the stacked lifts together, and thus by repeated operations, rapidly producing heel-piles for theheel compressor".

in carrying out the invention the sheet leatherboard, or other heel stock material,

is first divided into strips, which, for the style of heel having more or less taper, may be of varying Widths. fter the strips have been produced, a plurality of them, the number varying in accordance with the number of lifts in the heel to be built and graded as to Width or equal in Width in accordance With the style of the heel to be built, are laid side by side on a suitable support. and a series of heel-lift blanks are simultaneously cut from their ends, one blank from each strip. It will be obvious that when graded strips are employed for making a pitched heel of the general type hereinbefore named, the entire series is laid side by side in sequence in accordance with their Widths, the widest strip at one end of the series and the narrowest at the other end. Each series of lifts thus obtained are then superposed and secured together, preferably by paste, in the form of a heel pile. Later the heel piles may be nailed and compressed. It will thus be seen that in practising the present method no stock of blanks. is required as individual heels are built as fast as, but no faster than, blanks are produced for making them. Furthermore, those skilled in the art Will recognize that the method may successfully be employed in making heels of any desired height or style by varying the number or character of the strips from which the blanks are cut.

A machine in which there is provision for procuring successive series of lifts, collecting each series in a stack, pasting. them, and finally nailing the stacked lifts as above set forth, is described in my co-pending application Serial No. 735,750, filed December 9,

1912, from which the present application is a division, the steps constituting the present V a series of strips of heel-stock material, by

V a row of dies, preferably graded as to area,

which are actuated vertically to cut the entire series of lifts simultaneously, and then moved longitudinally with a lift retained in each die to a position above a suitable support comprising a row of shelves each in a different horizontal plane, On arrival in this position the series of lifts are ejected fromrthe dies and deposited on the shelves in a sequential row in accordance'with their areas. Thereafter a lift collecting'finger engages the lifts by moving in the line of the row through slots in the shelves by which operation the lifts are slid edgewise past each' other and thus stacked on an assembling bed beneath the shelves. Meanwhile the lifts are pasted on one face by being i swept past paste brushes located between the shelves, the liftcollecting movement placing the pasted and unpasted faces of the lifts against each other. The-stack thus formed is then advanced by the collecting'finger I I along the assembling bed to a nailing mechheel pile.

2. The method of making heels which includes producing simultaneously, from the ends of a series of strips of heel-stock material graded as to width, a series of heel-lift blanks graded as to area, and superposing and securing said blanks on each other in a single heel-pile of stepped formation for the production of a pitched heel.

3. The method of making heels which includes producing successive series of heellift blanks from the ends of a series of strips of heel-stock material, each series of blanks composed of one from each strip, and superposing and securing each series ofl blanks successively in an individual heel. p1 e.

4. The method of making heels which includes severing sheet, heel-stock material into strips, severing simultaneously heellift blanks from the ends of a series of said strips, one blank from each strip, and superposing and securing said blanks in a single heel pile.

The method of making heels which in-' cludes severing sheet, heel-stock material into strips of graded width, simultaneously producing from ends of a series of said-strips a series of blanks suitable for heel-lifts graded as to area and composed of one blank from each strip, and collecting and securing saidblanks in a single stack of stepped formation for the production of a pitched heel. 4 6; That step in the manufacture of shoe heels which consists in severing a series of heel-lift blanks, adequate for the production of a single heel, simultaneously from the ends of a series of unconnected strips of heel-stock material, one blank from each strip.
